The point is that the Jews are the original indigenous people of Judea. They had kingdoms and kings there. They fought Assyrians, Babylonians, Hittites, Egyptians, and more. The Jewish holiday of Hanukkah commemorates the successful struggle to liberate their land from the Syrian Greeks. The Jews revolted against the Roman Empire several times. Many were exiled, but each day for two thousand years they prayed to return to their land and never gave up claim to it. Each year they end the holiday of Passover with the declaration “next year in Jerusalem”.
The Arabs are indigenous to Arabia, not Judea. Arab armies conquered the land in the 7th century. It was conquered subsequently by others and was ruled by Crusaders and Caliphates and eventually fell under control of the Ottoman Turks. Through this whole long history, no Palestinian entity ever came into existence and there is no time when the Jews ceased insisting they were the sole rightful owners of the land. You may reject the unique divine right of the Jews to the land as explicitly granted in books holy to Jews, Christians, and Muslims, but it’s hard to deny the numerous passages in those books constitute an irrefutable land title.
